SPECHliCATION forming part. of Letters Patent No. 768,820, dated August 30, 1904. Application filed December 18, 1903. Serial No. 185.618. (No model.)

To all whom it may concern:

Be it known that I, Enwann A. Rtx, a citizenof the United States. residing in the city and county of San Francisco and State of (alit'ornim have invented new an-dvuseful lmthe following is a specification.

.\Iy invention relates to improvements in j lubricating machinery and the like.

My invention comprises details of construction. which will be more fully explained by reference to the accompanying drawings, in whichl*igure 1 is a longitudinal vertical section of my device. 'Fig. 2 is aperspcctive view of a capsule.

In motors driven by steam and air. and especially by the latter, large quantities of moisture are carried by the gases into the cylinder and valve and other mechanism. This moisture condensing washes away a great lubricate such machines. and this is particularly the case with rock-drills. so that undue wear and cutting soon take place to the great detrimentot' the machinery. Itv is therefore necessary for the best preservation of the delicate machmeryt-o introduce into such machines a lubricant which has suliicient body to adhere to the various parts and which will not be washed away by water. (Irease is the only thing proper for this purpose. It is a dillicult matter to introduce grease by means of such Iubricators asa re ordinarily titted upon machines. and in the transfer of grease as ordinarily put up nto a lubricator much dirt and dust are liable to be carried in with it. In drills which are lubricated by the use of v oil a great deal of dirt is also carried into the f drill mechanism, so much so that the principal wear arises from this dirt. An ordinary lubricator will not stand upon the rock-drill, but will break. 'Ihcretore the employces will use a can and inject oil into the air-hose of a drill before they connect the hose with a machine. and when. the air is turned on it is trusted to blow the oil into the drill; but the end of the hose is often draggedabout in the .dirt previous to the introduction of the oil, and when the connection hasbcen madethe 5 dirt will be carried through the mouth of the hose and into the drill.-

My invention enables me to measure the quantity to be applied and avoids carrying oil-cans into mines. Further, I am enabled to furnish a sulli ciently pure product without danger of sul'isequent adulteration.

A rcpresen ts a capsule or package of any suitable or desired sizeand material adapted to coin tain a definite or measured charge of grease. This package is preferably made independent and suliiciently exymusiblegso that when placed in a receiver. as will be I'IQI'ClDilftlI' described. its edges will be forced outward by any internal pressure. and thus form a suli'iciently tight joint with the interior of the receiver. These packages A are charged with a grease of good quality. and upon the top of the grease may .be placed a disk having a smaller diameter than the interior of the package. An exterior cover 2. completes the package, and these packages are made up in any uantities ready for sale and use. In order to properly apply the grease in these packages. I have shown a receiver 4. which may be of any suitable form or shape corresponding with the shape of the packages. In the present case I have shown these packages as in the form of shortcylinders, and the receiver 4 is of similar shape. having an interior diameter just suflicient to admit one of the capsules or packages after its cover has been removed, the 'capsule being inserted with its mouth toward the bottom of the receiver. The bottom of this receiver has an annular channel madearound it. as shown at 5, and this channel communicates with the part to be lubricated.

As shown in the present case, I have especially designed the device for application to drills operated by-air under pressure. The aii' contlucting pipe or hose is connected with the receiver below the bottom, and the annular channel opens directly into the space through which the air passes to the drill, so that as the grease is forced into this passage the air will blow it into the. drill and auto- .matically apply it to all parts needing luI)ri-- the device as re nireda movable ilun etfi may he emploved. For convcnicnce i have shown this plunger as is-ing screw-threznhsi.

so that by a tnrr. or partial turn of the sen-a the capsule or packag c ntaining the grease will be slightly compres ed. and the follow resting upon the bottom of the receiver and having an annular passage between it and the sides. of the package suhstantlally comes- 2. A lubricating devicecomprising the e tination with a receiver having a passage ie ng to the parts to he lubricated. of a grea container fitting said passage and contain a disk whose diameter is sutliciently less tl the inner diameter of the container to for:

I l i ci-rcumscribings;mace through whichthc gre Y is e ected in the. form of a hollow cohunm:

dent with the channel around the iottoi'n of the receiver, it will be seen that the gradual emptyingof the package will allow the grease to he forced through the annular channel and into the air-passage. pansihilit v ot' the sides of the package or capsule are such that if. there is any air. steam. or other pressure from within it will act to force these sides out against the interior of the receiver and will thus form a comparativelytight joint in the same manner as: etl'ected by what is known as "cup-packing By this construction {here will be no waste or danger of introducing dirt. as would he the case if the lubricant were taken from a large package and placed in the grease-cop. The quantities used can be known by reason of the number of packages furnished. and waste or loss can be checked. The can also be gradually introduced to the part to be lubricated by occasional turns of the screw plunger, and when the charge has been exhausted it is only necessary to remove tize screw and the emptied package, with its foilower, and to introduce a fresh one.

The flexibility and ex- I pressure means for ejecting the grease ft the container. A
